On the eve of a secret military operation, an assassin's bullet strikes President Seth Jerrison. He is rushed to the hospital, where surgeons struggle to save his life. At the same hospital, researcher Dr. Ranjip Singh is experimenting with a device that can erase traumatic memories. Then a terrorist bomb detonates in the operating room. It quickly becomes clear that the electromagnetic pulse generated by the bomb amplified and scrambled Dr. Singh's equipment, allowing a random group of people to access one another's minds. And now one of those people has access to the president's memories.
